what is the cosine of 3.14 ?

Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.

Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.

Cosine is 0.766

You mean, you have the cosine, and want the angle? That is called arc-cosine, often written as cos-1x. Your scientific calculator should have a "shift" key or something similar, which you press, followed by the cosine key. That will give you the inverse cosine or arc-cosine.
